What's the difference between your Sketcher Options....

[bsurfN99]

I was wondering if anyone could shine some light on the differences between the sketcher options. Specifically I'm wondering what the difference between sketch positioning options are. You have Positioned, sliding or isolated. What do these different options do to you sketch? I always used positioned but I can't see a difference between positioned and sliding.


thanks for your help...

A positioned sketch is truely a great thing to have. In a Sliding Sketch, the origin of the sketch is pretty much fixed wherever it was when the sketch was created. This means that, when you go to re-use a sketch (as you would in a PowerCopy or UserFeature) you have to make sure that there no constraints that refer back to the origin of the sketch (that includes no Horizontal or Vertical constraints either).

With a Positioned Sketch, the origin an orientation of the sketch can be linked to a 3-D point and set of lines/planes. Then, when you use the sketch in a PowerCopy, the user just picks the new origin and orientation, and your sketch is positioned correctly.

An Isolated sketch is just that, Isolated. You cannot change it's orientation, position, or plane.

You can move, rotate isolated sketch with the compass.
They are not linked with any plane...but you can turn them into sliding or positioned one...

what is an isolated sketch?

how do you create them? why?

 

[catiajim]

You can isolate a sketch after you create it. Simply right-click on the Sketch, go to Sketch Object, and select Change Sketch Support, and select Isolated from the drop-down list.

I'm not really sure why you would do this. The major power of V5 is in maitaining the history of the geometry.

Thanks, Jim.

But I'm not sure why anyone would do this.

 

[catiajim]

Neither am I. I do, however, have a number of V4 users that insist on isolating all of their V5 Geometry. They just don't get it.

I've only met one guy that does that. It does eliminate alot of errors! I guess it's kinda like riding a bicycle - you never have to worry about running out of gas.

it does eliminate a lot of error! created by the user ?

Positioned sketch are good, try to work with them ! And try not to make so many errors...
